Ahh Gerard. Welcome to the kludge that is the ASP.NET event model!

In ASP.NET, *nothing* happens until the user requests a page. When they do, everything happens between the time that they request the page and the time that it is displayed on the browser. From a simplistic viewpoint, everything is done at page load time.

So you have to cunningly write the Page_Load event to handle the first time a user pulls up the page, and every other time that the user refreshes the page because they've clicked a button or made a selection in a dropdownlist.

>>I just re-read your question and it occurred to me that you might be asking how to implement a simple drop-down list control and then refresh a grid that is already on the page with data from a child table.
>>
>>This is not difficult at all in .NET. Simply change the DataSource property of the grid in the DropDownList's SelectedIndexChanged event to whichever table you want to display.

>>>>Gerard, this can be done on a web form but it will require a lot of javascript along with the server-side code. Using an iframe, you can trigger a popup web browser window with the javascript:onClick event, or you can make a second web request (or web service request) from the onClick event, retrieve the grid, then manually re-arrange the exising content and insert the grid's HTML.
